For producing hot mix asphalt<\/strong><\/em>, road constructors use VG bitumen<\/strong><\/em>. Viscosity bitumen<\/strong><\/em> is a type of bitumen with many uses. This bitumen is thermoplastic which makes it flexible in warm climates and hard and fragile in cold regions. Viscous bitumen<\/strong><\/em> is also thick and adhesive. Its adhesion allows it to combine with other materials that create durable surfaces for the roads. Manufacturers produce viscosity bitumen<\/strong><\/em> at refineries distillation towers using aeration with vacuum batuum. In this article, we will explain the different types of VG bitumen<\/strong><\/em>, its definition and measurement.<\/p>\n

What is viscosity bitumen?<\/h2>\n

Various bitumen products<\/strong><\/em> have different gradings and many applications in making asphalt<\/strong><\/em>, road pavings and concrete sidewalks. Manufacturers produce viscosity bitumen<\/strong><\/em> by applying aeration through a vacuum batuum at the distillation towers. Viscosity grade bitumen<\/strong><\/em> (also called VG bitumen) has its most uses in building hot mix asphalt.<\/p>\n

The viscosity of bitumen<\/strong><\/em> is an important factor in choosing the right product for road construction. Furthermore, because of the exact grading of VG bitumen<\/strong><\/em>, its products are more prominent than penetration bitumen.<\/p>\n

\"What<\/p>\n

History of viscosity grade bitumen<\/h2>\n

The history of viscosity bitumen<\/strong><\/em> is associated with evolutionary methods of road construction<\/strong><\/em> and attempts to improve road longevity and the quality of its surface. At first, the road constructors<\/strong><\/em> used normal bitumen to build roads. However, in the 20th century, they began using petroleum-based bitumen for road construction<\/strong><\/em>.<\/p>\n

(Click to learn more about Penetration Grade Bitumen<\/strong><\/em><\/a>.)<\/p>\n

In that era, the traditional methods for grading bitumen<\/strong><\/em> were based on bitumen\u2019s penetration degree. In this method, the experts determined if the bitumen<\/strong><\/em>was soft or hard, measuring the penetration depth of a standard needle when it penetrated bitumen<\/strong><\/em> under specific conditions. However, as the demand for constructing more advanced roads<\/strong><\/em> increased, this method proved to be incomplete.<\/p>\n

(Click for information on\u00a0bitumen price<\/a><\/strong><\/em>.)<\/p>\n

In fact, penetration bitumen<\/strong><\/em> cannot predict bitumen\u2019s performance at high temperatures that result in road grooving, cracks and dilapidation. As a result, Road engineers conducted more research on grade bitumen<\/strong><\/em> products and prioritized determining the viscosity of bitumen<\/strong><\/em>.<\/p>\n

\"History<\/p>\n

The introduction of viscosity bitumen in the late 20th century<\/h3>\n

At the end of the 20th century, the concept of grading bitumen products<\/strong><\/em> based on their viscosity was introduced. This concept provided a more comprehensive understanding of bitumen\u2019s behavior<\/strong><\/em> at different temperatures. Based on this grading system, the experts measured the bitumen\u2019s viscosity<\/strong><\/em> at 60 centigrades and could effectively predict the materials’ behavior at higher temperatures.<\/p>\n

Therefore, categorizing a bitumen<\/strong><\/em>based on its viscosity replaced the bitumen grading method by penetration. Today, the use of VG bitumen products<\/strong><\/em> is known and acceptable throughout the whole world.<\/p>\n

(Click for more information about\u00a0Pasargad Oil bitumen<\/a><\/strong><\/em>.)<\/p>\n

Various VG bitumen gradings such as VG10<\/strong><\/em>, VG20<\/strong><\/em>, VG30<\/strong><\/em>and VG40<\/strong><\/em>have better flexibility in terms of use. As a result, road engineers can choose the most suitable type of bitumen<\/strong><\/em>according to their projects\u2019 requirements and local weather.<\/p>\n

Using VG bitumen<\/strong><\/em> improves road performance and durability. Therefore, many consider the introduction of viscosity bitumen<\/strong><\/em> an important point in road construction.<\/p>\n

\"The<\/p>\n

Viscosity grade bitumen\u2019s chemical formula<\/h2>\n

No bitumen product<\/strong><\/em> has an exact formula, because bitumen is a complex mixture of hydrocarbons. That is why bitumen<\/strong><\/em>composition is different for every product and includes thousands of different molecules. Therefore, bitumen products<\/strong><\/em> are mainly composed of carbon hydrogen but also have oxygen, nitrogen and sulfur in them.<\/p>\n

\"Viscosity<\/p>\n

Viscosity grade bitumen composition<\/h3>\n

As we explained in the previous paragraphs, VG bitumen<\/strong><\/em> is a complex mixture with multiple hydrocarbons. That is why there is no exact common formula for all bitumen products<\/strong><\/em>. But they have some ingredients in common that are categorized as:<\/p>\n

It is worth mentioning that the balance between these components affects the physical traits of viscosity bitumen<\/strong><\/em>. Different bitumen products have different compositions. Also, various manufacturing processes can affect this balance.<\/p>\n

\"Viscosity<\/p>\n

Saturants<\/h4>\n

Saturants<\/strong><\/em>are the most stable compounds that are mainly made of linear or chain hydrocarbons.<\/p>\n

\"Saturants\"<\/p>\n

Aromatics<\/h4>\n

Aromatics<\/strong><\/em>are flat chain hydrocarbons that help with bitumen<\/strong><\/em>resilience and its ability to reform after deformation.<\/p>\n

\"Aromatics\"<\/p>\n

Resins<\/h4>\n

These are flat polar hydrocarbons that play an important part in the adhesive qualities of the bitumen<\/strong><\/em>. Resins cause the bitumen to stick to the aggregates in asphalt mixtures<\/strong><\/em>.<\/p>\n

\"Resins\"<\/p>\n

Asphaltene<\/h4>\n

Asphaltenes<\/strong><\/em>are components with the heaviest molecular weight and are mainly composed of dense multi-chain aromatic hydrocarbons. They also include ingredients such as sulfur, nitrogen and oxygen which cause the bitumen<\/strong><\/em>to harden.<\/p>\n

\"Asphaltene\"<\/p>\n

Production of viscosity grade bitumen<\/h2>\n

The process of producing VG bitumen<\/strong><\/em> has multiple steps, including petroleum extraction, refinement and measuring the VG<\/strong>of bitumen<\/strong><\/em>. Therefore, in this section, we will explain the overall process of viscosity bitumen<\/strong><\/em> production.<\/p>\n

Remember that bitumen specifications<\/strong><\/em> can be different based on the petroleum quality and the products\u2019 desired properties.<\/p>\n

\"Production<\/p>\n

Extracting Petroleum<\/h3>\n

The first step in viscosity bitumen production<\/strong><\/em> is extracting petroleum from petroleum wells. Petroleum is composed of different hydrocarbons including heavy portions of bitumen. Manufacturers use petroleum to produce bitumen products like VG bitumen<\/strong><\/em>.<\/p>\n

\"Extracting<\/p>\n

Petroleum distillation<\/h3>\n

After manufacturers extract petroleum<\/strong><\/em>, they place it in a refinery and expose it to atmospheric distillation. This process warms the petroleum and causes it to evaporate and condense at different portions and different temperatures. Lighter portions of petroleum<\/strong><\/em>including gasoline will be expunged at lower temperatures, but the heavy bitumen<\/strong><\/em>will sediment at the bottom of the container.<\/p>\n

\"Petroleum<\/p>\n

Vacuum distillation<\/h3>\n

Manufacturers expose the heavy petroleum<\/strong><\/em>left after atmospheric distillation to the vacuum distillation process. This process expunges lighter abortions of petroleum without causing heat cracks in the bitumen<\/strong><\/em>.<\/p>\n

\"Vacuum<\/p>\n

Air blowing<\/h3>\n

For viscosity bitumen<\/strong><\/em> to have desirable traits, manufacturers expose the vacuum residue to the air-blowing process in which warm air passes through the residue. This method causes a certain reaction which increases the physical and functional traits of bitumen<\/strong><\/em> and allows it to be durable in different weather conditions.<\/p>\n

\"Air<\/p>\n

Grading bitumen\u2019s viscosity<\/h3>\n

At the final stage of production, the manufacturers grade bitumen<\/strong><\/em>based on its viscosity. First, they heat the bitumen to standard 60 Celsius. Then, they measure its viscosity. Based on the degree of bitumen viscosity<\/strong><\/em>, VG bitumen products have different categories such as VG10, VG20, VG30 and VG40.<\/p>\n

\"Grading<\/p>\n

Types of viscosity grade bitumen<\/h2>\n

Understanding and choosing a bitumen<\/strong><\/em>with the right viscosity<\/strong><\/em> is very important in road construction and maintenance. Manufacturers categorize these hydrocarbon materials based on their viscosity<\/strong><\/em>at 60 Celsius. Their consistency is also very important in determining their uses. The most common viscosity bitumen grades<\/strong><\/em> are VG10<\/strong><\/em>, VG20<\/strong><\/em>, VG30<\/strong><\/em>and VG40<\/strong><\/em>.<\/p>\n

\"Types<\/p>\n

VG10 and VG20<\/h3>\n

VG 10 bitumen<\/strong><\/em> has a lower viscosity. Therefore, it is more suitable for applying in cold regions. Additionally, it is flexible in lower temperatures. However, VG20<\/strong><\/em>is mainly applicable in warm climates and is a standard choice for most road construction projects<\/strong><\/em>.\"VG10<\/p>\n

VG30 and VG40<\/h3>\n

On the other hand, in places with higher ambient temperatures, VG30<\/strong><\/em>and VG40<\/strong><\/em>are more ideal bitumen products. These bitumen grades are more stable at higher temperatures and prevent road deformation in high-traffic roads. That is why VG40 bitumen<\/strong> products are often useful in high-traffic roads at high temperatures.<\/p>\n

\"VG30<\/p>\n

The Importance of choosing the bitumen with the right viscosity<\/h2>\n

It is best to always choose a bitumen<\/strong><\/em>pure carat based on regional climate and traffic load. You should always remember that paving<\/strong><\/em>longevity and performance are heavily dependent on this choice. That is why having a comprehensive understanding of VG bitumen<\/strong><\/em> helps you make informed decisions for choosing the best bitumen product<\/strong><\/em> for your construction projects.<\/p>\n

For choosing the right bitumen for roads<\/strong><\/em> and their increased longevity, always consider its use according to the local environment and traffic.<\/p>\n

\"The<\/p>\n

The pros and cons of using viscosity grade bitumen<\/h2>\n

Today, VG bitumen<\/strong><\/em> products are more in use than penetration bitumen because experts test them carefully in two stages. First, they test the penetration degree of bitumen<\/strong><\/em>at 25 Celsius (which is the normal temperature). However, since this testing is unreliable in warm temperatures, experts will test the bitumen\u2019s viscosity<\/strong><\/em> at both 60 and 135 Celsius.<\/p>\n

The results of this testing show that VG bitumen<\/strong><\/em> can endure 25 to 135 temperatures that cause road fatigue cracks in construction. Furthermore, the temperature sensitivity might also be a result of a bitumen viscosity test<\/strong><\/em>.<\/p>\n

\"The<\/p>\n

Saving time and expenses<\/h3>\n

Producing VG bitumen<\/strong><\/em> can save time and money because the number of tests for determining bitumen\u2019s viscosity<\/strong><\/em> is significantly lower than the tests performed for bitumen penetration. For instance, viscosity bitumen test<\/strong><\/em>\u00a0has only 7 steps. On the other hand, specifying a bitumen’s penetration degree takes place during 14 steps.<\/p>\n

\"Saving<\/p>\n

Viscosity grade bitumen is more durable<\/h3>\n

Pavings<\/strong><\/em>made of VG bitumen perform better because the amount of viscosity at 135 Celsius gives us a general idea about the bitumen\u2019s mixture<\/strong><\/em> and compression. Consequently, the paving\u2019s longevity<\/strong><\/em>will improve.<\/p>\n

Using viscosity bitumen<\/strong><\/em> is suitable in regions with high traffic.<\/p>\n

\"Viscosity<\/p>\n

What are viscosity bitumen properties?<\/h2>\n

Manufacturers categorize VG bitumen<\/strong><\/em> products by their unique physical and chemical traits that make them usable for different applications, especially in road construction<\/strong><\/em>. In this section, we will explain some of these key traits.<\/p>\n

Special traits of VG bitumen<\/strong><\/em> might be different among its various grades. For example, VG10, VGA 20, VG30 and VG40 all have different levels of viscosity that affect their performance under certain conditions. These traits turn VG bitumen<\/strong><\/em> into a very versatile and useful substance for construction projects.<\/p>\n

\"What<\/p>\n

What is the viscosity of bitumen?<\/h3>\n

As is evident from the name, viscosity bitumen<\/strong><\/em> is the bitumen\u2019s degree of viscosity and significantly impacts the bitumen\u2019s performance. Bitumen\u2019s viscosity measures its resistance to deformation and flow. Higher VG bitumen grades<\/strong><\/em> are more resistant to deformation and are ideal for use at higher temperatures or heavy traffic roads.<\/p>\n

\"What<\/p>\n

Temperature sensitivity<\/h3>\n

Manufacturers produce viscosity bitumen<\/strong><\/em> in a way that it has good performance in a wide range of temperatures. For instance, at lower temperatures, VG bitumen<\/strong><\/em> will remain flexible to resist cracking. However, it is also durable at high temperatures to resist grooving<\/strong><\/em>.<\/p>\n

\"Temperature<\/p>\n

Adhesion of viscosity grade bitumen<\/h3>\n

Bitumen<\/strong><\/em>has a strong adhesive trait that allows it to stick to aggregates and asphalt mixtures effectively. This trait is very important in road construction<\/strong><\/em> because it makes sure that the surface of the road<\/strong><\/em> remains firm in different circumstances.<\/p>\n

\"Adhesion<\/p>\n

Durability<\/h3>\n

Viscosity grade bitumen<\/strong><\/em> is well known for its durability and can withstand various weather conditions and heavy traffic loads. As a result, viscosity bitumen<\/strong><\/em> is a durable substance in road construction<\/strong><\/em> and other uses.<\/p>\n

\"Durability\"<\/p>\n

Resistance to water<\/h3>\n

VG bitumen<\/em><\/strong> is resistant to water. That is why it is an effective substance in waterproofing applications. Furthermore, viscosity bitumen\u2019s resistance to water<\/strong><\/em> helps to protect the surface of the roads against any water damage.<\/p>\n

\"Resistance<\/p>\n

Elasticity<\/h3>\n

Bitumen<\/strong><\/em>is elastic which allows it to regain its original form after deformation. This trait is particularly useful against high and heavy traffic roads.<\/p>\n

\"Elasticity\"<\/p>\n

Viscosity grade bitumen uses<\/h2>\n

VG bitumen<\/strong><\/em> is a type of bitumen that road constructors mainly use for building roads. Therefore, it is suitable to apply in road constructions and higher quality asphalt pavings. But what exactly are the uses of viscosity bitumen<\/strong><\/em> products?<\/p>\n

\"Viscosity<\/p>\n

VG10 bitumen appliances<\/h3>\n

VG10<\/strong><\/em>has a penetration degree of 80\/100 and is a good choice to cover the surface of roads. Additionally, it is a necessary component in producing bitumen emulsion and other modified bitumen products<\/strong><\/em>. VG10 is a suitable replacement for penetration grade 80\/100 bitumen<\/strong><\/em>.<\/p>\n

Furthermore, using this bitumen<\/strong><\/em>has its advantages. For example, you can apply VG10<\/strong><\/em>below 30 Celsius and it has an absolute viscosity of 800. Also, compared with VG30<\/strong><\/em>and VG40<\/strong><\/em>, it has a better penetration value.<\/p>\n

\"VG10<\/p>\n

What are the viscosity grades of asphalt: VG20 uses<\/h3>\n

VG20 bitumen<\/strong><\/em> is a good product to use in pavings at lower temperatures and high regions. You can use this bitumen in the average temperature of 30 to 37 Celsius.<\/p>\n

\"What<\/p>\n

What is meant by VG 30 bitumen?<\/h3>\n

VG30<\/strong><\/em>is a component in producing extra heavy bitumen pavings. These pavings have to endure heavy traffic. Therefore, road constructors<\/strong><\/em>often use VG30 products to build roads. Overall, road construction, buildings, insulations, and liquid products are the common fields that use VG30<\/strong><\/em>. VG40<\/strong><\/em>is also suitable to apply in temperate climates and is a good replacement for using 60\/70 bitumen<\/strong><\/em>.<\/p>\n

\"What<\/p>\n

Bitumen vg 30 specifications: VG30 benefits<\/h4>\n

Using VG30<\/strong><\/em>has some benefits. For example, you can use it at higher temperatures, because it has good durability. It also has high viscosity<\/strong><\/em>which is more suited for use with clay. Additionally, road constructors<\/strong><\/em> also use it in humid areas.<\/p>\n

\"Bitumen<\/p>\n

VG bitumen uses: VG40 appliances<\/h3>\n

Road constructors usually use bitumen<\/strong><\/em>with a penetration degree of 40\/50 in high-traffic areas such as intersections, highways, toll roads and truck parking lots. This type of bitumen<\/strong><\/em>has high viscosity. Therefore, it is good to use on roads with heavy traffic<\/strong><\/em> and areas that are exposed to high tensile strength loads. VG40 is also a good replacement for 40\/50 and 30\/40 penetration degree bitumen<\/strong><\/em>.<\/p>\n

\"VG<\/p>\n

Benefits of using VG40<\/h4>\n

Using VG40 bitumen<\/strong><\/em> has some benefits. For instance, it can endure temperatures higher than 40 Celsius and has an absolute viscosity of 3200. VG40 is also an ideal choice for use in building high-traffic roads<\/strong><\/em>.<\/p>\n

\"Benefits<\/p>\n

Consistency of viscosity grade bitumen<\/h2>\n

Consistency is a key feature in viscosity bitumen<\/strong><\/em> that turns it into a suitable substance to construct roads, build damp Insulations and other infrastructures. However, bitumen\u2019s consistency<\/strong><\/em> depends on different factors including its grading, storing conditions, etc which we will explain below.<\/p>\n

If used properly, VG bitumen<\/strong><\/em> is durable as a long-term solution to apply on roads to protect them against daily corrosion and rupture. It can also perform better in different weather conditions and high traffic.<\/p>\n

\"Consistency<\/p>\n

Bitumen grading<\/h3>\n

Higher viscosity bitumen products<\/strong><\/em> like VG30 and VG40 are more durable against grooving<\/strong><\/em>and high temperatures. They are also flexible at lower temperatures which makes them more durable. This resistance is especially useful in warm regions with very heavy traffic<\/strong><\/em>.<\/p>\n

\"Bitumen<\/p>\n

The conditions of using viscosity grade bitumen<\/h3>\n

Viscosity bitumen<\/strong><\/em> durability considerably depends on environmental conditions and the roads\u2019 traffic load. For example, in harsh weather and high-traffic areas, bitumen\u2019s longevity<\/strong><\/em> might be shorter. It may also need constant maintenance and changing multiple times.<\/p>\n

\"The<\/p>\n

Maintaining and caring for viscosity grade bitumen<\/h3>\n

If road maintenance workers regularly repair and maintain road surfaces, they can increase the durability of bitumen<\/strong><\/em>. These maintenance processes will include regular inspections for damages, on-time repairs, sealing road cracks and further paving. With the proper maintenance, bitumen<\/strong><\/em>paved roads can remain functional for decades which makes them an effective choice in the long term for infrastructure projects<\/strong><\/em>.<\/p>\n

\"Maintaining<\/p>\n

Viscosity bitumen price and purchase<\/h2>\n

The international bitumen industry<\/strong><\/em> is constantly evolving, and viscosity bitumen<\/strong><\/em> is one of its main products. Therefore, the price of VG bitumen depends on several factors such as worldwide economic conditions, technological advancements and its production process<\/strong><\/em>. That is why understanding factors such as these can provide a better understanding of the dynamics of the VG bitumen market<\/strong><\/em>.<\/p>\n

\"Viscosity<\/p>\n

The effects of worldwide economics on the price of VG bitumen<\/h3>\n

The most important Factor in VG bitumen\u2019s price<\/strong><\/em> is the international economic conditions. When the world economy is constantly prospering, the demand for infrastructure projects increases. Therefore, the increased demand for these projects will increase the viscosity bitumen price<\/strong><\/em>.<\/p>\n

\"The<\/p>\n

The price of petroleum<\/h3>\n

Another factor that is significant in the pricing of viscosity bitumen<\/strong><\/em> is the price of petroleum. VG bitumen is a result of petroleum refinement. So, if there is a change in petroleum’s price, bitumen\u2019s price<\/strong><\/em> will also change.<\/p>\n

\"The<\/p>\n

Production costs<\/h3>\n

Another factor that affects viscosity bitumen\u2019s price<\/strong><\/em>is its production costs. These costs include the expenses of producing raw materials, workforce and required energy for refining petroleum. If any of these expenses increase, the price of viscosity bitumen<\/strong><\/em> will also increase.<\/p>\n

\"Production<\/p>\n

Market\u2019s demand for VG bitumen<\/h3>\n

The market\u2019s demand for purchasing viscosity bitumen<\/strong><\/em> plays an important role in determining its price. Especially, if the increase in demand is from the emerging economies that are developing their infrastructures, it can increase the VG bitumen price<\/strong><\/em> considerably.<\/p>\n

\"Market\u2019s<\/p>\n

Technological advances<\/h3>\n

If the rate of technological advances in producing bitumen<\/strong><\/em> is fast, it can affect its price. For instance, more efficient production techniques for VG bitumen<\/strong><\/em> can reduce production costs and potentially decrease the viscosity bitumen price<\/strong><\/em>. The suppliers in the bitumen industry are also an important factor in determining the price of viscosity bitumen<\/strong><\/em>.<\/p>\n

\"Technological<\/p>\n

Saybolt viscometer<\/h2>\n

Viscosity<\/strong><\/em> is the opposite of fluidity and a parameter for bitumen\u2019s resistance to flow. The higher the viscosity of a liquid bitumen<\/strong><\/em>, the closer it is to a semi-solid state. In terms of consistency, bitumen adhesives<\/strong><\/em> with low viscosity smooth aggregate particles easily instead of creating a thin uniform layer on them.<\/p>\n

Therefore, high viscosity bitumen<\/strong><\/em> doesn’t allow much condensation. As a result, the mixture shows heterogeneous features and low stability. For testing liquid bitumen<\/strong>viscosity<\/strong><\/em>experts perform a Saybolt viscosity test.<\/p>\n

\"Saybolt<\/p>\n

Saybolt tests<\/h3>\n

The Saybolt universal viscosity<\/strong><\/em> and Saybolt FUROL viscosity are special standard tests that specify the amount of kinematic viscosity<\/strong><\/em>. FUROL is an abbreviation for fuel and road oil.<\/p>\n

In both of these tests, experts use a Saybolt viscometer<\/strong><\/em> to determine a bitumen’s viscosity by measuring the time it takes for 60 milliliters of bitumen<\/strong><\/em>to pass through a graded pipe at a certain temperature. Experts usually perform this viscosity test of bitumen<\/strong><\/em> at 38 and 40 Celsius.<\/p>\n
